What is Corroding Lead?
Corroding Lead (UNS L51110, ASTM B29) is high-purity soft lead, 99.94% Pb and above, supplied as ingot, sheet, extrusion and castings. It is the standard feedstock for white lead pigment, storage-battery oxide and other lead chemicals, chosen where purity and formability matter more than strength: 12.5 MPa tensile, 6 MPa yield, 30% elongation, 4 HB and a machinability rating of 55. It has no useful structural strength, creeps under its own weight at room temperature, and requires lead-hygiene controls. For sulfuric-acid service, copper-bearing Chemical Lead (L51120) is the usual alternative. Corroding Lead has a density of 11.34 g/cm³ (0.41 lb/in³), heavier than 99% of solder & low-melting alloy grades. It melts at 327°C (621 °F). Corroding Lead has a yield strength of 6 MPa (0.87 ksi) and a tensile strength of 13 MPa (1.89 ksi) — weaker than 96% of solder & low-melting alloy grades. Elongation at break is 35% and the elastic modulus is 14 GPa (2.03 Msi).

Working with Corroding Lead
Is Corroding Lead easy to machine?
Cuts with almost no force but smears and loads tools — use sharp high-rake HSS, wide chip clearance, no coolant mist, and capture swarf/dust under local exhaust for toxicity control.
Can Corroding Lead be welded?
Joined by lead burning (oxy-hydrogen or oxy-acetylene torch with pure-lead filler strip) or by soldering; keep fume extraction, no flux needed for burning.
Can Corroding Lead be formed, bent or molded?
Extremely formable cold — rolling, bossing, hammering and extrusion all work, and lead recrystallizes at room temperature so it never work-hardens; cast easily at 350–420 °C.

Corroding Lead — frequently asked
What is Corroding Lead used for?
Corroding Lead is typically used for battery oxide feedstock, lead pigment production and chemical lead compounds. In short: highest-purity lead grade; chemical feedstock quality; softest of the family.
What is the yield strength of Corroding Lead?
Corroding Lead has a typical yield strength of 6 MPa (0.87 ksi) and a tensile strength of 13 MPa (1.89 ksi) — weaker than 96% of solder & low-melting alloy grades. Strength varies by condition: see the 2 listed tempers.
Is Corroding Lead easy to machine?
Reasonably — machinability is rated good (55/100, better than 74% of solder & low-melting alloy grades). Cuts with almost no force but smears and loads tools — use sharp high-rake HSS, wide chip clearance, no coolant mist, and capture swarf/dust under local exhaust for toxicity control.
Can Corroding Lead be welded?
Yes — weldability is rated good (60/100). Joined by lead burning (oxy-hydrogen or oxy-acetylene torch with pure-lead filler strip) or by soldering; keep fume extraction, no flux needed for burning.
What surface finishes work on Corroding Lead?
No anodizing or plating in practice; surfaces self-patinate to grey PbO/PbCO₃, can be painted with alkali-resistant primers or left bare in sulfuric-acid service.

What is the maximum service temperature of Corroding Lead?
Corroding Lead is rated for continuous use to about 100°C (212 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
How much does Corroding Lead cost?
Corroding Lead is a standard-cost solder & low-melting alloy ($$), cheaper than about 71% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
